A guide to where you can drink the tap water across the world.
If you’re wondering if it’s safe to drink the water where you’re going then this at a glance guide will help you prepare. Although we have tried to be thorough, this is not necessarily a comprehensive guide and is subject to change.
Bear in mind that many hotels will purify water on the premises for their guests, especially the larger chains.
You may also find that you acclimatise to water quality after an extended stay in a country. This doesn’t mean that you are immune to water borne diseases such as cholera and e.coli so be very careful.
Unsafe water can be prepared by bringing to a rolling boil (bringing to a boil and then simmering for a few minutes) and then leaving it to cool in a clean container. You can then use this water to drink or prepare food with.
Strange tastes in water can often be either cleaning treatments such as chlorine or sometimes local mineralisation such as calcium.
If in doubt, stick to bottled water…
As a general rule most of Western Europe is perfectly safe to drink the tap water. Certain cities (Paris, Barcelona, London) have either a high mineral content or a high chlorine content which is used to purify the water. It is, however, perfectly potable, although it might taste funny.
In some regions the water will be mineral water quality (French Alps, Scottish Highlands, Italian midlands, Norway, Sweden).
Most of Eastern Europe is fine for drinking water but in some places caution may be best exercised.
Bulgaria, Romania, Cyprus, the Balkan States and the former Soviet States all have slightly dubious reputations for drinking water. However this is not to say it isn’t drinkable.

South Africa, is safe to drink the water in most big towns and cities. If in more rural areas it would be best to check with a local.
Southern African countries including Zimbabwe, Botswana, Namibia, Mozambique all have variable water quality. In most major cities and bigger hotels the water will be fine to drink. Although this can change with the availability of water in the area. Sometimes waste water is recycled, sometimes it’s piped in from outside. If in doubt check with a local.
